In accordance with the geneml features of this invention, the finer bubbles gamer-\- mind in the action of the ele wwmsed to coalesce infco larger has been found that the coalescence cf the smaller bubbles may be brceght aboubliy applying to the surface of the electrolyte a finely 'clividecl bouyent material. For this p'urposefinely divided cork 01' cork granules have been *lound to be particularly satisfactory, and a layer of granular gen gas in the solufiion causes a disag ees) m escaping flispliccticic, filed Hamil 4l, .9%.
